It only takes ten moves to open this box! Easy to build, every piece is a simple rectangle. No curves, no circles, no holes, no dowels. All pieces are pre-cut and labeled. The usable space inside is fairly small, so you could put a couple of rings in, or a few small coins. You could build this in an hour or so! This is a great puzzle box to make as a first attempt. Instructions come with patterns to add to the box, additional patterns are available below.
